Official measurements from the Hong Kong Observatory confirm a daily maximum of 27°C on July 31, 2026, under the influence of a subtropical ridge that brought generally fine conditions with moderate southerly flow and limited daytime heating. This value aligns with regional station readings and climatological expectations for late July, when typical highs reach 30–32°C but can moderate due to cloud cover, higher humidity, or post-typhoon effects from earlier systems like Noul. Trader consensus at 100% for 27°C reflects the final verified data release, as prediction markets aggregate real-capital assessments of official records rather than forecasts. Revisions remain possible only if the Observatory issues corrected observations from its primary site or adjusts for instrumental factors, though such changes are rare after initial publication.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 31 Jul '26.
The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Max (deg. C)" the specified date once information is finalized in the relevant "Daily Extract", available here: https://www.weather.gov.hk/en/cis/climat.htm
This market can not resolve until data for this date has been published.
The resolution source for this market measures temperatures in Celsius to one decimal place (eg, 9.1°C). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is initially published for this market's timeframe will not be considered for this market's resolution.Official measurements from the Hong Kong Observatory confirm a daily maximum of 27°C on July 31, 2026, under the influence of a subtropical ridge that brought generally fine conditions with moderate southerly flow and limited daytime heating.
